Frequently asked questions

How much will $15,000 grow at 12% for 5 years?

How long does it take $15,000 to double at 12%?

Using the Rule of 72, money doubles approximately every 6.1 years at 12% annual return. Starting with $15,000, you'd reach $30,000 in roughly 6.1 years. At 12% over 5 years, your money multiplies 1.82× — doubling 0.9 times.

Is 12% a realistic annual return?

12% is an aggressive assumption — above the S&P 500's ~10% historical average. Individual stocks, sector ETFs, or leveraged positions may achieve this, but it's not reliable for planning purposes. Financial planners typically use 6–8% for retirement projections. Use 12% to model optimistic best-case scenarios.
